http://www.cancunmx.com/nitelife_frm.shtml Aren't a few(at least?) of these places no longer in business?
Fat Tuesday is the most glaring of these. That, I think was the most popular locale on the list that was shut down.
Tequila Boom is gone as well. So is Mambo Cafe (due to recent fire) and Over 30 in the Hotel Zone (courtesy of Wilma) and I believe Over 30 downtown has shut down too. Also gone is the Senor Frogs Bar Leaping Tour. And I do believe Mango Tango is no more as well.
Winner Sports Bar is also no longer in existence, Planet Hollywood is now in La Isla not Plaza Flamingo, and I've never heard of the "Life" club (anyone know anything about this place?). As a fellow website owner though I will say it is difficult to keep up with all the changes that happen in Cancun and then to remember to update your pages. My page at: Cancun Club Status has a pretty good represenation of the current club situation, although it needs a little updating too.
looks like he's been working on it and trying to get it updated, and that's why he asked people to look at it and help him out.
Life was open briefly a few years back...the entrance was on the corner of onme of the buildings just before you got to the Party Center...right around that huge souvenir place.
